Description:

Washing the solid waste from the oil before the storage or other final disposal using various techniques:

==> Cold Water Flushing, simple technique, moderately successful, to wash large quantities of oiled debris with a high pressure hose to loosen and float away oil. The resulting oil/water mixture can then be treated via a separator

==> Warm/Hot Water Flushing to clean pebbles, gravel and sand contaminated with oil or emulsion, using standard mineral processing equipment coupled to a conventional oil/water separator.

==> High velocity steam jets directed onto an inclined, vibrating, perforated tray placed above a collector to trap oil and condensate, may be used to clean oil-contaminated sand. Possible use of demulsifier.

==> Solvent Extraction may be considered as a possible mean of removing oil from collected sand, pebbles and debris. Limited research has been carried out in relation to the use of this technique.
